@kayx23 Hi，I didn’t see any updates on the official website for this submission. Is it my problem?

[kayx23]

The site is built daily and not immediately on any merges into main I believe. Give it 24 hours and see if it updates.

@smileby @kayx23 I doubt that it goes with v 3.8.x or v 3.9 release as it was merged into the master branch. Neither 3.8 version nor the Next version contains the change.

Sorry, I don't quite understand how the website directory is generated. It may be my problem, but I can help modify it. Also, please tell me how to do it.

@yzeng25 @kayx23 please help check again
